Step 2: Cut and Dry Fit the Tiles

Cut a few tiles on the wet saw and lay them out on the floor for a dryfit. You should mix tiles from different boxes to account for the color variations.

Step 3: Apply the Thinset

Backbutter the tiles with thinset using a square-notch trowel. The slate tile thickness can vary up to 7/16" of an inch so add extra thinset if necessary to make up the difference. Hold the trowel almost vertically to get the maximum coverage of thinset.

Place spacers between each tile (Image 1). Sponge extra thinset off the top of the tiles before it sets (Image 2).
